Ralphy,
Posted more info on the thread you started about the Pinto Rack. In a nutshell, it is different and unless you are designing a new car (or redesigning to correct a design fault), the MustangII and Pinto racks will not interchange. The are very similar and serve the same function, but that is where the similarity ends.

Bumpsteer is a design issue and you can create problems by interchanging parts that aren't exact size duplicates. Bumpsteer is a relatively simple concept although the resolution can be pretty complicated. Resolution can be as simple as bolting on some different parts or as complicated as redesigning the entire suspension.

If you want to learn more, look at the Longacre or Woodward Steering sites
